The Gould's Belt Spitzer Legacy Survey will complete the census of star formation in molecular clouds within 500 pc of the sun. Imaging observations with IRAC and MIPS will provide the crucial data shortward of 200 microns to match the data from large projects planned with SCUBA-2 on the JCMT (450 and 850 microns) and SPIRE (200 to 500 microns) on Herschel. Together with the clouds surveyed by the Cores to Disks (c2d) Spitzer Legacy program and clouds studied by GTO/GO programs, these observations will complete the census of star formation regions within 500 pc. Relevant Spitzer data on Gould's Belt clouds, including previous GTO/GO data, will be processed through the c2d pipeline to produce a uniform, complete, and unbiased database for studies of local star formation. Scientific goals include the following: determine which of the many dense cores detected by SCUBA-2 have embedded stars and which are starless; compile the statistics of objects in different evolutionary stages to obtain timescales for these stages, a fundamental check on theory; use the large sample to control for effects of enviroment on star formation; assess the fraction of star formation in distributed and clustered modes, including the number in groups of various sizes; combine the MIPS data with the submillimeter data to study the physical conditions in extended structures with a goal of understanding the formation of dense cores. In this poster we discuss some of these goals in more detail, and present some preliminary results based on data acquired thus far. This project is supported by NASA-JPL under Research Support Agreement no. 1288820.
